FN2000 bug -

There's currently a bug with the FN2000's disarm ability (epic weapon for the trooper for those who haven't gotten the drop). As is, the ability is supposed to disarm enemies who have only one usable weapon completely and knock the currently equipped weapon from their hands if they have more than one equipped.

However, when the disarm ability kicks in, it sometimes disarms the enemy for one turn only while at other times it disarms the enemy for the remainder of the round. Is this supposed to be the case? I was under the impression that disarm will render the enemy weaponless for the entire round. Thanks.
